What is a Senior SDET and how is it different from a tester?<\/strong><br data-start=\"877\" data-end=\"880\" \/>A Senior SDET goes beyond executing test cases. They design automation frameworks, integrate tests into CI\/CD, use rich test evidence and influence release strategy, acting as both engineer and quality strategist rather than only a manual executor.<\/p>\n<p data-start=\"809\" data-end=\"1168\"><strong data-start=\"1175\" data-end=\"1236\">Q2. How did you move from manual testing into automation?<\/strong><br data-start=\"1236\" data-end=\"1239\" \/>I started by automating repetitive regression tests with Selenium and TestNG, parameterising test data, capturing screenshots and logs, and integrating suites into a CI\/CD pipeline. This shift made testing faster, more reliable and more impactful on release decisions.<\/p>\n<p data-start=\"809\" data-end=\"1168\"><strong data-start=\"1554\" data-end=\"1611\">Q3. Why is framework design so important for an SDET?<\/strong><br data-start=\"1611\" data-end=\"1614\" \/>A good framework makes tests maintainable, scalable and reliable. Using patterns like <a href=\"https:\/\/www.testleaf.com\/blog\/page-object-model-without-assertion-overload\/\">Page Object Model<\/a>, centralized test data, parallel execution and rich evidence helps teams run large suites across environments without constant firefighting.<\/p>\n<p data-start=\"809\" data-end=\"1168\"><strong data-start=\"1905\" data-end=\"1971\">Q4. How did your mindset change when you became a Senior SDET?<\/strong><br data-start=\"1971\" data-end=\"1974\" \/>My focus moved from \u201cDid this feature pass?\u201d to \u201cAre we testing the right risks in the right way?\u201d That meant risk-based testing, negative and edge cases, CI\/CD integration, secure test accounts and evidence-driven decision making.<\/p>\n<p data-start=\"809\" data-end=\"1168\"><strong data-start=\"2252\" data-end=\"2322\">Q5. What role does a Senior SDET play in leadership and mentoring?<\/strong><br data-start=\"2322\" data-end=\"2325\" \/>A Senior SDET mentors junior testers on automation best practices, architects long-term frameworks, represents QA in product discussions and drives continuous improvement by analysing flaky tests, pipeline metrics and defect trends.<\/p>\n<p data-start=\"809\" data-end=\"1168\"><strong data-start=\"2604\" data-end=\"2673\">Q6. What advice do you have for testers who want to become SDETs?<\/strong><br data-start=\"2673\" data-end=\"2676\" \/>Don\u2019t stop at execution.
